Be it known that We. JOHN K. E. DIFFEN nnnrrnn, VinLon P. `i T1r.LrA.\1s. and MIRIAM S. F. lVrLnmMs. respectively. citizens of the United States. Rumeniv, and Canada. residw ing' :it Baltimore. in the county of 'Baltimore City and State oi Maryland, have invented cert-nin new und useful Ii'nprovements in Automobile Parking Devices, or" which the following' is a specification.

This invention relates to pailring;y devices lor automobiles. and hnsspecinl referenceto in1}' 1ovo1neuts on the parking device for automobiles, 4for which application for Letf l5 ters Potent of the United States was led hy Miriam 5l. ll'. Williams und J. K. E. Diffenderlier on h'l'orch 24. 1922, under the Se rial Number 546,241, :ind resulted in Patent Number 1,475,369, issued November 6, 1923.

One important object of this invention is to improve nndvsimpli'liy the general con- .struction of the device illustrated in the prior application,

Engineer-ingr experience has disclosed that certain ofthe features of the parking device of the prior application could, while' re` taining the general principles there in-f volved. be changed. in their detailsiand or; rangements to greatly decrease the cost ol' volved.

A third import-.mt objectof the invention is to provide e, device of' this chornoter wherein the control ot the dili'erent olfiero` tions will he accomplished by en extremely simple mechanism.

A fourth important object of the invention is to provide a` device of this" ieracter wherein the movement of o single controh ling lever in selected directions lvvill'so control the mechanism of the invention that, when the sume is applied to :mi automobile, the automobile will he raised or lowered from the ground and muy he moved side 'Ways in either direction at will. and Without the operator leaving his seat.

speciicollyy claimed. installation and simplify the mechanism inl i e meters olreierence indicate like fifth import-ont object of the invention is to providei novel lira-king means for con- 55 trolling the' lateral movement of the out-omobile.

A- ninth important object of the invention is to provide en improved safety mechanism for the single control lever which netnates the several clutches in thedevicc. i

With the above end other 'objects in View es Willbe hereinafter apparent, the inlven`- tion consists in general of certztin novel details of construction and combinations of parts hereineter more fully described, illustrated in the nccompfniying' drawings sind In the accompanying'drawing' like elterpnrts in the several views, and: i 85 l l, is :i tide elevation oi :in automohile thorium' the device applied thereto, :1nd .illustrating in dotted liners the general outlino'ol1 the in.ention.` V Fig'. is n plan view ot o" portion of an' automobile 'Frame showing` the inventionIiir- .stalled tliereon. 5i

In the embodiment ot the invention herein illustrated. it will he seen that there is disclosed an ordinary touring car 20 having a power plant 2l. This touring,r ear is provided with the usual trame 22 which supports on each side a pair ot jacks, two ot' these jacks being positioned tor 'ardly and two rearwardly. Each ot these jacks iucludes a lixedjack head or housingl 23, which is firmly seein-ed tothe side members ot' the 'trame Q0, and in which is provided a pair ot vertically alined hearings Q4.' Between the hearings 24 in each housing` or jaclthead is located a. worm wheel 25 havin;r a threaded opening extending therethrough for the receptionv ot' the threaded upper end 26 ot' a. jack slamilard. This worm wheel is supported ahove by suitahle anti-friction thrust hearings Q7, and the standard projects downward and carries on its lower end a yoke QS wherein is journalled a shaitqQS) supporting a ground wheel 30 provided with a suitable tire 31 of rnhloervor the like. The heads 2?, on each side are connected hy an upper longitudinal shaft 32 which carries adjaiifent each end a, worm 33 meshing with the respective worm wheel 25. There is also provided a transverse shaft 3l which is suitably geared to the` shafts S2, as hy ,bevel earings Thus rotationot one of the shafts 32 affects rotation of the other', and

consequently, through the act-ier. of the i A 'A ,i

.to slide vertically through said gear.

Worm and worm wheel. the jacks will he raised or lowered according to the direction in which the respective shafts 32 rotate.

Driven from the power plant 2.1 is a shaft 36 n'hereon is revolubly mounted a'fpair ot confronting bevel gears 37 and f-ltl. each of which is provided with a Clutch tace indicated respectively at 39 'and 40. Splined on the shaft 3G between the clutch faces 3f) and 4l) is a clutch member l1. From this construction it will he seen that when thev me1nherfll is moved in, one direction. the bevel gear 3T will be loelted on the shalt 36 while. movement of the melnloer il in the opposite direction. will lock the lievel gear 53S on the shaft 36. These two bevel lears are so arranged that they mesh with a bevel fear 42 on opposite sides thereof. Under these circumstances1 it will he obvious that this hevel gear 42 may he rotated in one direetion or the other in accordance with the engagement of one or the other ot the gears il? and 38 to the shaft 3G. This gear 42 is revolubly mounted on the lower end ot im inclined shaft 43 which is suitably journalled in the main housing 44 of the driving mechanism tor the parkingV device. Furthermore. the gear 42 is provided on its upper end with a clutch member 45 and splined on the shaft 4:3 is a clutch nienihor 46 loy means ot which the gear t2 may he clutched to and unclutched from the shaft 43. At the upper end of this shaft 43 there is fixed a bevel gear 47 which meshes with a similar hevcl gear L18 tixed upon one ot the shafts 32.

It will now he obvious that by means ot the construction just described.,they rotation ofthe shaft 3G can he transmitted to the sha lt 32 in'such manner that this shaft nan be caused to revolve in either direction at will. hy the proper manipulation ot the clutches.

Similarly there is provided on the oppo site side ot the housing 44 a bevel gear 49 wherewith the two gears 537 and 3S also mesh. This gear is mounted on an inclined shaft 50 so as to revolve freely thereon, and is provided with a clutch tace. 51 cooperating with a clutch member 52 spliued on tho shaft 50. At the upper end ot the sha fl 5l) there is provided a hovel gear 53 which meshes with a hevel gear h4; carried ou a shaft r[his shalt 55 extends into one ol the jack heA ds as clearly shown in Figures 6 and 7, anf carries on its inner end a hevel gear 56 which meshes with a similar bevel gear 57 having a polygonal opening:l `therethrough for the reception ot a vertical slid.- ing shaft 58. the shaft thus rotatingwith the gear 57 while at the saine time it is free one of the vokes 28 there is provided a housing 59 into which the lower end ot the shall. 58 extends. On this lower end is a gear (30 whichV meshes with a bevel gear. (31 fixed on one ot the shafts 29, it being preferable that lll( desired tocontine the invention to. the exact torni herein shown and describei'l, but it is wished to include all such as properly come within the scope claimed. i v A lVe claim: n
